OVEN-DOOR.

SPECFICATION forming part of Letters Patent N o. 694,700, dated March 4, 1902.

Application filed October 30,1901.. Serial No. 80.560. (No model.)

To all whom t may concern:

Be it known that I, FRANK H.VAN HOUTEN, a citizen of the United States, residngatFishkill-on-the-Hudson, inthe county of .Dutchess and State of New York, have invented certain new and useful Improvements in Oven- Doors; and I do hereby declare the following to be a full, clear, andexact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and tothe letters of reference marked thereon.

The present invention relates to improvements in oven-doors, the invention being particularly designed for application to bakers ovens, although features of the invention may be advantageously employed in connection with other types of ovens or like compartments Where vertically-swinging doors are employed.

The invention consists in certain novel details of construction and combinations and arrangements of parts, all as Will be now described and pointed out particularly in the appended claims.

Referring to the accompanying drawings, Figure l is a front elevation of an oven-door embodying the present invention. Fig. 2 is a side elevation. Fig. 3 is a central vertical section through the frame. Fig. 4f is a similar section with the door, front plate, and Window in position. Figs. 5 and 6 are detail side and front elevations of one of the j amb-pieces.

Similar letters of reference in the several figures denote the same parts.

The frame indicated b'y the letter A in said drawings is preferably an integral casting, adapted to be built into the oven-wall and having a front or finishing iiange A of 'substantially rectangular contour. The central opening is the door-opening, and on each side thereof is achamber A2, opening at the front through the flange A and extending some distance above the top of the door-opening. In the Walls of the frame between the chambers A2 and main door-opening recesses a, Fig. 3, are formed, such recesses opening out to the front of the frame and adapted for the reception of bearings for the journals of door.

the door. The frame as thus far described may be built with the wall of the oven and the working parts of the door subsequently applied, to which end the door itself, lettered B and preferably formed of sheet metal, is mounted on a tubular shaft or section of tube O of sufficient length to project into the chambers A2 at the ends. Then in position, this shaft is journaled in bearings d, located in the recesses a and formed on the upper ends of jamb-pieces D,Figs. 5 and 6.' These jambpieces D are formed with flanges D', against which the edges of the door rest, and they are adjustably secured to the side pieces of the franle A by set-screws E, .passing through slots d' in the j amb-pieces, whereby they may be separately adjusted to accommodate themselves to the angle of the door or so as to make a tight fit should the door Warp, Wind,

or be distorted through the action of the heat or from other cause. The hubs or bearings d on the jamb-pieces serve to position the upper ends of the jamb-pieces in addition to serving as the bearing for the door-shaft, and

,they are adapted to be held in place in the openings a by a front plate H, which also closes the part of the door-opening above the rlhe front plate is secured in place by set-screws h and at the center is formed with a window-opening closed. by a hinged frame H,p`rovidedwith a transparent panel H2, the said frame being held closed by a button h2 or other simple fastening device.

The ends of the tubular shaft C, projecting into the chambers at each end of the dooropening,are adapted for the reception of counterbalance-weights K, preferably adjustably mounted as follows: The weights K are mounted on stems 7c, passing through transverse holes in the shaft and through similar holes in the enlarged portions Z of the bolts L, located Within the shaft. The outerends of the bolts project from the endsof'the shaft and have nuts M applied thereto, whereby the bolts may be moved longitudinally of the shaft and the stems of the weights bound in any desired position of adjustment.

It Will be observed that if the front plate be removed the door-jamb pieces, itc., may

be readily removed to permit of easy access tothe oven for repairs, the. The construction is such that the working parts are very light and strong, while the balance-weights at each end of the shaft add to the durability oi' construction and also allow the door to be operated from either side.

Extending downwardly from the door-frame are two brackets N, each having a series of notches m and a series of pins m, constituting supports for adjustable arms O. The brackets are preferably connected at the lower ends by a rod or brace N', and the arms support a shelf P, constituting an adjustable peel-rest. As the most convenient means for adjusting the peel-rest the arms O are provided with pins o, which take in the notches m, while the inner ends of the arms rest under the pinsl Thus the baker can by m on the brackets. the simplestmanipulation raise and lower the rest to suit his convenience, and at no position of adjustment can the rest by any possibility interfere with the working of the oven-door, nor does the employment of the rest require any change in the masonry of the oven.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination with the door-frame having the central door-opening with the recesses in said frame at each side of said opening, of the jamb-pieces having projections extending into said recesses, a door journaled in said projection of the jamb-pieces and a removable front plate having a central window and closing said recesses and the space above the door, whereby by the removal of said front plate the door and working parts may be removed without disturbing the frame; substantially as described.

2. The combination with the door-frame having the door-opening, and the door journaled in said opening on a horizontal axis, of the jamb-pieces against which the door rests when closed, adjustably mounted on the sides of the frame whereby they may be independently adjusted to compensate for warping or winding of the door; substantially as described.

3. The combination with the door-frame having the door-opening,r and door journaled in said opening, of the jamb-pieccs journaled on an axis coincident with the axis of the door and ad justably connected with the frame at their outer ends whereby they may be set to compensate for the warping or Winding of the door; substantially as described.

4. The combination with the door-frame having the door-opening, and the jamb-picces having hubs at the upper ends seating in the frame and means for adjustably connecting the lower ends of the jamb-pieces to said frame, of the door and a shaft on which it is mounted passing through the hubs 0f the jamb-pieces whereby the door and jamb-picces may be turned aboutacommon axis; substantially as described.

5. The combination with the door-frame having the central door-opening, chambers at each side thereof and recesses in the walls between said opening and chambers and the jamb-pieces having hubs projecting into said recesses and adjustably connected with the frame at the lower ends, of the shaft project:- ing through said hubs into the chambers, the door secured to the central portion of the shaft, the counterweights secured to the ends of the shaft in the chambers, and the front plate removably mounted on the frame and closing said recesses and the portion of the door-opening above the shaft; substantially as described.

6. In an oven-door, the combination with the door mounted on a tubular shaft, of counterweights for the door mounted on stems projecting' transversely through the ends of the shaft, the screw-bolts surrounding said stems within the shaft and the nuts on said bolts and bearing against the ends of the shaft for locking the stems and Weights in adjusted position; substantially as described.
